Gander: the Preliminary Design and Evaluation of an AR+Tablet System for Geospatial Analysis

We explore the combination of headworn augmented reality (AR) displays and handheld tablet devices to support geospatial analysis. In this paper, we present the design of an AR+tablet prototype named Gander. Gander supports the selection of attributes when building a predictive model for some geospatial phenomenon, such as water pollution is correlated to the proximity of large cities, and the comparison of these models. We conducted a walkthrough evaluation with five experts in geospatial analysis and GIS tools. The experts identified strengths and weaknesses in Gander’s design. We propose new design changes such as the pancake plot, rank-based visualization, and reducing steps on the tablet interface.
